The fan-made patches for Tiberian Dawn and Red Alert have a feature to deinterlace videos during runtime. Currently, OpenRA plays the videos interlaced, which look noticeably worse.
Are there any plans to add the code that deinterlaces the videos for OpenRA? It should be possible to do by tweaking the code of the movie player to decode it properly.
The video decoder naturally deinterlaces, but we then fake the interlacing by drawing a stripe pattern overlay. You can disable this locally by adding DrawOverlay: False under the VqaPlayer widget definitions in the mods/<mod>/chrome/<file>.yaml files.
There are no plans to disable the fake interlacing in our default mods.
This would be nice as a checkbox option under the Visuals/Graphics section in the options menu.
Edit: I remember the play station versions of TD and RA both had interlacing removed from all videos.
That's not likely to happen (adding a bounty does not mean that the feature will be added). We made a design choice to display the videos as they are now, and adding a bunch of checkboxes to change minor UI style points is poor design.
